Specification of Letters Patent.

Patented May 4, 1915.

Application filed. April 7, 1914. Serial No. 830,127.

To all whom it may concern Be it known that I, HARRY VAUGHAN RUDSTON READ, a subject of-the King o-f-Great Britain and Ireland, and residing at Craigs Court, Gharing Cross, London, S. W., England, have invented certain new and useful Improvements in and Relating to Devices for Aerating Liquids, of which the following is a specification.

The invention relates to improvements in the aerating device describedin my patent specification No. 1056151 of 18th March, 1913. In this device the valve lever of the sip-hon is depressed by the continued movement of the hand lever of the aerating device and it is possible for pressure to accumulate in the spout and adjacent parts of the siphon head before the valve lever is depressed.

The object of the present invention is to provide means whereby such an occurrence may be prevented.

The invention consists in the improved aerating devices hereinafter described or indicated and particularly pointed out in the claims.

Referring to the accompanying drawings :-Fig] re 1 shows a side elevation of a single siphon charger with the siphon valve lever held down before the capsule is discharged; Fig. 2 showing a corresponding view ofter the stop or catchhold-ing down the valve lever has been automatically released by continued movement of the hand lever; Fig. '3 shows a front elevation of an aerating device fitted with the holding-down stop and adapted to charge two siphons simultaneously. Fig. 4 being a section of the line AB of Fig.3, and Fig. 5 a perspective view of the member enabling both siphon valve levers to be held down by a single catch.

Where desirable the same reference symbols as in the patent above referred to are employed to denote corresponding parts.

In carrying the invention into effect according to one form as shown in Fgs. 1 and 2, the siphon with spout, is, and valve lever, m, is inclosed as in my above-mentioned patent, in a casing, the removable cover, d, only of which is shown in the figures; the charged capsule, r, acting as a reservoir for the aerating gas likewise, is arranged point downward in its support or cradle While the joint-making block, u, provided with its guide-rods, t, is operated by the hand lever, 9, pivoted at 8 to the cover, cl, which thus serves as a base member, and rigid with the short arms, 7, connected to the block, u, by the links, 4, all as before.

According to the present invention, however, a special holding-down catch or stop member is pivoted at 11 to the head of the charger cover, this member comprising on one side of its pivot, a curved tail, 12, and on the other side a counterweight, 13, the action of which may be assisted by a spring, such as 1 1.

The action of the device described is as follows z-With the hand lever, 9, in the position shown in Fig. 1, the valve lever, m, is depressed with the finger and the catch member turned about its pivot, 11, until the tail, 1-2, enters the space in the siphon head casing just above the valve lever (see Fig. 1), which is thereby held in its depressed position with the siphon valve open; at the same time the tendency of the valve lever to rise under the action of the usual spring retains the tail, 12, in place against the action of the counterweight. On then operating the hand lever, 9, the contents of the capsule are discharged and pass freely through the open valve into the siphon; continued movement of the hand lever, however, causes the pin, 10, attached to 'it to strike the valve lever and depress it slightly, thereby releasing the tail, 12, and allowing the catch member to become inoperative by assuming the position shown in Fig. 2. The hand lever is thus substituted functionally for the holding down member until discharge of the capsule is completed; the hand lever may then be returned so as to allow the valve lever to rise in the ordinary man ner and close the siphon valve.

Referring to Figs. 3 to 5, a modified form of holding-down device is shown applied to an aerating apparatus adapted to charge tw siphons simultaneously.

The two siphons of usual construction are inclosed in a double casing, 6, provided with detachable heads, 03, 'held together by suitable members such as the plate, 15, and stay, 16. In order to provide for detachably securing the heads, d, to the bodies, 6, of the casing, locking rings, 17, are provided of the cross-section shown in Fig. 4;; in particular the rings are each provided with an inturned edge, 17 which at an appropriate point, 17", is cut away to allow the passage of the projections, cl, on the detachable heads, d. Locking is then preferably effected by holding the parts in correct posi tion with one hand and rotating the rings with the other hand about their axes through equal angles in opposite directions by means of one of the finger pieces, 18, and intermeshing gear segments, 19, one on each ring, the device as a whole forming a detachable joint of the bayonet type.

The support or cradle, n, for the capsule, is placed midway between the two heads, d and is carried by a bent plate, 20, as shown in Fig. I. This support is provided on each side with a guide-way, 21, of V-shaped crosssection in which slide corresponding guides, 22, attached to the discharging and jointmaking member, u, the latter being of elongated form with suitable means, such as the washer, w, in the center for making joint with and discharging the capsule, and an internal duct, 2, leading to the two ends, which are similarly adapted for making joint with the spouts of the siphons.

The joint-making member, u, is operated from the hand lever, 9, pivoted at 8, by way of the links, 1, connected to the guides, 22.

In order to open the siphon valves before discharging the capsule, a lever, 23, (see Fig. 5) pivoted at 2a, is provided with a transverse rod, 25, bearing upon the two siphon valve levers, which lever may be depressed so as simultaneously to open both valves and be held in its depressed position by a single hook or catch, 26, (see Fig. 4) pivoted to the plate, 20, and provided with a counterbalance, 27 the catch 26 may thus be regarded as the active member of the holding-down device and corresponds to the curved tail 12 of Fig. 2.

On operating the hand lever, 9, in the manner described in detail above, the contents of the capsule are simultaneously discharged and distributed between the two siphons and by continued movement of the hand lever, a pin or lug, 28, thereon, with a beveled face strikes the hook, 26, and itself holds down the lever 23 until discharge of the capsule is completed.

Having now described my invention, what I claim as new and desire to secure by Letters Patent 1. In apparatus for aerating liquids, a base member attachable to the liquid-containing receptacle to be charged, said member having means for holding a charged reservoir; means for holding open a valve controlling the outlet of said receptacle together with means for discharging the contents of said reservoir through the outlet of said receptacle, said means including a manuallyoperated member, appropriate movement of which serves to render said holding-open means inoperative.

2. In apparatus for aerating liquids, a base member attachable to the liquid-containing receptacle to be charged, said member having means for holding a charged reservoir; means for holding open a valve controlling the outlet of said receptacle together with means for discharging the contents of said reservoir through the outlet of said receptacle, said means including a manuallyoperated member, functionally substitutable by appropriate movement for the active member of said holding-open means.

3. In combination in a device for aerating the contents of a liquid-containing receptacle, a base member attachable to said receptacle; means mounted on said base member for connecting a charged reservoir to the outlet of said receptacle; means for liberating the contents of said reservoir; means also mounted on said base member for holding-open a valve controlling the outlet of said receptacle together with a manuallyoperated member, movement of which serves successively to actuate said connecting and liberating means and to render said holdingopen means inoperative.

at. In apparatus for aerating liquids, a base member attachable to the siphon to be charged, said member having means for holding a charged capsule; means for holding down the valve lever of said siphon together with means for discharging the contents of said capsule through the siphon spout, said means including a manually-operated member, appropriate movement of which serves to render said holding-down means inoperative.

5. In combination in a device for aerating the contents of a plurality of liquid-containing receptacles, a casing and cover therefor and means for simultaneously locking therewithin a plurality of receptacles, said'means including locking members with intermeshing gears.

' 6. In combination in a device for aerating the contents of a plurality of liquid-containing receptacles, a base member attachable to said receptacle and mounted thereon, a single instrumentality common to said receptacles for holding open the valves controlling the respective outlets of said receptacles.

7. In combination in a device for aerating the contents of a plurality of liquid-containing receptacles, a base member attachable to said receptacles and mounted thereon, means for holding open the valves controlling the outlets of said receptacles together with a single instrumentality for rendering said holding-open means inoperative.

8. In combination in a device for aerating the contents of a plurality of liquid-containing receptacles, a base member attachable to said receptacles, said base member 5 having means for holding a charged reservoir; means for holding open the valves controlling the outlets of said receptacles together with means for discharging the contents of said reservoir through the outlets 1 of said receptacles, said means including a manually-operated member, appropriate movement of which serves to render said holding-open means inoperative.
